Application iied February 17, 1919. Serial No'. 7,277,553. i

T0 all whom it may concern Be it known that I, EDGAR HEAD, citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Irrigator'Shut-Offs, and declare the following to be a full, clear, and exact description of the same, such as will -enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an irrigator shut off shown in the accompanying drawings and more particularly described in the following specification and claims.

The object of the invention is to provide a quick acting shut off adapted to compress the usual rubber tube employed in connection with irrigators, or other devices of a like character, whereby the discharge of fluidl may be instantly controlled without danger of cracking the tube, due to the operation of the shut off device.

'With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement Vof p'arts and in the details of construction hereinafter described and claimed, it being understood that changes may be made `in the precise embodiment of the. invention herein disclosed without departing from the spirit of the same.

In the accompanying drawings forming part of this specification Figure 1 is a side elevation of the device mounted upon a rubber tube, in turn secured to an irrigatore-shown in dottedV lines. v c

Fig. 2 is a side elevation of the device, showing the tube compressed thereby.

Fig.,3 is a sectional view on line 3-3 of Fig. 2. Y

iig. 4 is a plan view of therdevice.

Fig..5 is a detail sectional view taken on line 5-5 of Fig. 1.

Referring now to the letters of reference yplaced upon the drawings A, denotes an irrigator of usual construction suspended from a standard B. C denotes a rubber tube connected with a discharge neck extending from kthe bottom of the irrigator. l

D, designates the shutoff device, sleeved upon the rubber tube,-consisting of a casting E, with an open neck El, through which the rubber tube C extends, and an integral fan-shaped portion E2 having an arc-shaped perimeter E3 which the rubber tube is forced to overlap as will be hereinafter explained.

IF, denotes a swinging member provided with an operating handle F1 and arms F2 having inwardly directed trunnions F3 journaled in the wall of the casting E.

G, indicates a rollermounted upon ashaft G1 supported by the arms FZVof the swingin g member. The surface of the roller Gr is slightly arc-shaped in longitudinal section, and the outer surface of the arc-shaped portion of the casting E is Icorrespondingly formed in cross-section (see Fig. 3), the ob- ]ect being to avoid cracking the rubber tube along the line of its folded edges, when compressed between said parts. The surface of the roller and said coperating portion of the casting E, between which the rubber tube is gripped, mayhowever be parallel, and flat if desired.

Having now indicated the several parts by reference letters, the construction and operation of theV device will be Vreadily understood upon reference to the; drawings and without further detailed explanation.

What I claim is:

l. device of the character described comprising a Ycasting having an arc-shaped portion and an opening for the passage of a tube, a compressible tube extending through the opening in said casting, a swinging member journaled in said casting, a roller jouriialed in theV swinging member adapted uponY the manual operation of the swinging member to ride over the arc-shaped portion of the casting, whereby the tube ymay be compressed between the roller and ther arc-shaped portion of the casting, the discharge of iuid through said tube being thereby cut ofi".

2. device of the character described comprising a casting having an arc-shaped portion with a projecting sleeve adapted to receive a collapsible tube, a bifurcated swinging member having trunnions journaled in the wall of said casting, and a roller journaled in the swinging member, adapted when manually actuated to coinpress the tube between the roller and the arc-shaped portion of said casting.

3. A device of the character described comprising a casting having an arc-shaped which a collapsible tube may extend Whereloy it may overlap the aro-shaped portion shaped portion of the casting upon manu- 10 ally rocking the swngngmemher.

In testimony whereof, I sign this speciof the castillo' a swnvng member pvotecl foation in the presence of two Witnesses.
